"As of March 11, 2013, we had reserved for issuance 9,372,283 shares of our common stock issuable upon the exercise of outstanding stock options at a weighted-average exercise price of $2.25 per share. Subject to applicable vesting requirements, upon exercise of these options, the underlying shares may be resold into the public market. In the case of outstanding options that have exercise prices that are below the market price of our common stock from time to time, our stockholders would experience dilution.
Our warrants may result in dilution to our stockholders.
Our March 2011 and April 2011 warrants to purchase a total of 3,207,000 shares of common stock at a current exercise price of $0.65 per share contain so-called full-ratchet anti-dilution provisions. Our March 2010 and December 2012 warrants to purchase a total of 7,938,000 shares of common stock at current exercise prices of $2.20 per share and $1.90 per share, respectively, contain so-called weighted-average anti-dilution provisions. These anti-dilution provisions will be triggered upon an issuance by us of shares of our common stock or common stock equivalents at a price per share below the then-exercise price of the warrants, subject to some exceptions.
To the extent that these anti-dilution provisions are triggered in the future, we would be required to reduce the exercise price of all the warrants on either a full-ratchet or weighted-average basis, which would have a dilutive effect on our stockholders at the time."
